Theresa Greenfield, the Democratic challenger to Iowa Sen. Joni Ernst, said racial bias is built into American law enforcement, but she doesn’t fault individual officers.

“We have systemic racism in all of our systems and have for generations, including our policing system,” Greenfield argued at the Iowa Senatorial debate on Monday evening. “But that is not saying that our police officers are racist.”

The Iowa State Patrol did not immediately respond to Fox News’ request for comment. Neither did the police departments from Des Moines or Cedar Rapids, the two most populated cities in Iowa.

DEM CHALLENGER TO IOWA SEN. ERNST SHIFTS LANGUAGE ON PACKING SUPREME COURT

Greenfield, whose father-in-law was a member of the police force, thinks officers should undergo racial-bias and de-escalation training and that chokeholds should be banned.

Ernst, a former combat veteran who is seeking her second term in the Senate, “doesn’t believe” there is systemic racism in law enforcement but does think there’s work to be done.

She co-sponsored Republican South Carolina Sen. Tim Scott’s Justice Act, which penalized state and local police departments that don’t use body cameras. The bill also called for limiting chokeholds, among other things.

The bill failed with a vote of 55 yeas and 45 nays, which included two Democrats crossing the aisle. Sixty votes were needed to send the bill to the House.

WHITE HOUSE TELLS IOWA UNIVERSITIES TO RAMP UP CORONAVIRUS TESTING

The issues of defunding the police and law and order have grabbed some of the spotlight in this year’s election after George Floyd, a Black man, died on May 25 after a White Minneapolis police officer knelt on his neck for nearly nine minutes.

Floyd’s death sparked both peaceful protests and riots amid calls for pulling funding from police departments. Civil rights groups have long complained that police officers stop, question and fine or arrest minority groups more often than their White peers.

Greenfield for weeks remained silent on defunding the police despite calls from Ernst for her to denounce the matter. On Aug. 30, she came out against the policy.
